She refuses to wear them. • Barbie and Ken accidentally break a beaker full of some chemical. Instead of risking getting in trouble they quickly clean up the mess with paper towel and throw it in the garbage.

  27. Compare and Contrast 2 Chemicals Build a table that answers the following things about your assigned chemicals: 1. Appearance 2.First aid measures 3. How to dispose it. 4. Storage 5. Fire Fighting Measures 6. Spill Below your table, write a paragraph that compares and contrasts your 2 chemicals. On the back of the paper draw and color a safety diamond for each one of your chemicals
